Apple to add new battery recalibration feature with iPhone 11 series with iOS 14.5
Apple iPhone 11 series users will receive messages throughout the battery recalibration process
While the battery health data is being updated, you might find a message in Settings > Battery > Battery Health.This message reads, “Your battery health reporting system is recalibrating Maximum Capacity and Peak Performance Capability. This process may take a few weeks. Learn more…” There are other possible messages that might appear during the recalibration process.
The recalibration of maximum battery capacity and peak performance capability takes place during regular charging and could take several weeks to complete. While this process is going on, the displayed maximum capacity percentage will not change. Peak performance capability might be updated, but most users may not notice this. When the recalibration is complete, “maximum capacity percentage and peak performance capability are updated. The recalibration message will also be removed, indicating that the process is complete.”
In a small number of cases, the recalibration might not be successful. This will result in the posting of a new battery service message. If that does happen to you, an Apple authorized service provider will be able to restore full battery capacity and performance by replacing the battery free of charge. Apple makes it clear that seeing such a message does not mean that there is a service issue and the battery can still be used until it is replaced. Because current battery reporting on the iPhone 11 series might not be accurate, Apple says to wait for the recalibration process to be complete before deciding whether you need to contact an Apple authorized service provider.
